February 12, 2024 - The development of bumblebee models was motivated primarily by the discovery that mechanisms in string theory (and subsequently other quantum theories of gravity) can lead to tensor-valued fields acquiring vacuum expectation values. Bumblebee models are different from local U(1) gauge theories.

A quantum system with only 51 charged atoms can take on more than two quadrillion different states. Calculating the system's behavior is child's play for a quantum simulator. But verifying the result is almost impossible, even with today's supercomputers. A research team from The University ...

August 8, 2019 - The notion that scientists proved bumblebees can't fly has a long legacy.

Nature - X-ray scattering study suggests insects' wing muscles work by mechanism shared with vertebrate muscle.

Aerodynamic forces and power requirements in forward flight in a bumblebee (Bombus terrestris) were studied using the method of computational fluid dynamics. Actual wing kinematic data of free flight were used in the study (the speed ranges from 0 m/s to 4.5 m/s; advance ratio ranges from 0–0.66).

January 15, 2016 - A simulation of a flying bee shows that insects don't expend extra energy to maintain lift in turbulent air flow.

You have probably all heard, at one point or another, that the bumblebee is nothing short of a scientific enigma – that our greatest minds, who have managed to place a man on the moon, have yet to explain the aerodynamics of the bumblebee’s flight. Unfortunately (or rather fortunately) ...

A characteristic of the movement of such a quantum particle is that, in addition to the smaller jumps, also significantly larger jumps occur. This phenomenon can also be observed in the flight of bees and in unusual fierce movements in the stock market. While simulating the dynamics of a complex ...

May 7, 2009 - (PhysOrg.com) -- Brute force rather than aerodynamic efficiency is the key to bumblebee flight, Oxford University scientists have discovered.

A quantum system consisting of only 51 charged atoms can assume more than two quadrillion different states. Calculating the system's behavior is a piece of cake for a quantum simulator. Yet even w ...

December 21, 2023 - The flight of the bumblebee has long been a source of fascination, in part because the lift requirements cannot be explained by conventional steady fluid dynamics, and unsteady aerodynamic mechanisms must be invoked. In addition, viscous effects are important for the majority of flying insects, ...

Bumblebees are remarkable navigators. While their flight paths may look scattered to the casual eye, all that buzzing about is anything but random. Like the travelling salesman in the famous mathematical problem of how to take the shortest path along multiple stops, bumblebees quickly find ...

Flying animals are capable of navigating through environments of different complexity with high precision. To control their flight when negotiating narrow tunnels, bees and birds use the magnitude of apparent image motion (known as optic flow) generated by the walls.

June 28, 2016 - See how scientists use high-speed videography to investigate and learn from the clumsy flight of the bumblebee.

Abstract The emergence of agricultural land use change creates a number of challenges that insect pollinators, such as eusocial bees, must overcome. Resultant fragmentation and loss of suitable for...

July 30, 2013 - Myth: Bumblebee’s shouldn’t be able to fly. There’s an oft repeated “fact” that the humble bumblebee defies all known laws of physics every time it flaps its tiny little bee wings and ascends to the sky. Now obviously this is false, since, well, bumblebees fly all the time and if ...

August 8, 2011 - By Terry D. Johnson The myth that bumblebee flight is scientifically impossible persists today. Even some presidential hopefuls believe it. Don’t be fooled. This tale’s been floating around since the 1930s, back when aerodynamics was emerging from a science.

In quantum physics, measurements can fundamentally yield discrete and random results. Emblematic of this feature is Bohr’s 1913 proposal of quantum jumps between two discrete energy levels of an atom1. Experimentally, quantum jumps were first observed in an atomic ion driven by a weak ...
